Description
Technical field
It the utility model is related to a kind of multistage and allow pressure grouting anchor pole, belong to Geotechnical Engineering anchoring field.
Background technology
In the surrounding rock supporting in Geotechnical Engineering field, suspension roof support already becomes a kind of preferable supporting tool.But with
The continuous increase of difficulty of construction, the characteristics of roadway surrounding rock usually shows large deformation, crustal stress is high, when larger change occurs in country rock
During shape, because deformation energy at initial stage is larger, the deformation energy of roadway surrounding rock exceeds the scope that anchor pole is born, and anchor pole will be caused to lose
Effect, anchor pole can not just play substantial role, and tunnel, the safety in tunnel are by serious threat.Therefore, in surrounding rock supporting, need
Wanting a kind of, there is the anchor pole for allowing pressure to act on to carry out supporting.Though currently used pressure-relieving achor bar serve it is certain allow pressure to act on,
In the larger tunnel of deflection, allow pressure stroke is inadequate, and final anchor pole is still pulled off because surrouding rock deformation is excessive and loses branch
Shield effect, how to increase pressure-relieving achor bar makes pressure energy power and solution anchored end anchor force insufficient, farthest plays to allow and presses anchor
The effect of bar, this technical barrier are badly in need of solving.
China State Intellectual Property Office discloses an a kind of entitled " umbrella shaped support formula slip casting anchor on April 27th, 2016
Bar ", Application No. CN201521006211.2 utility application.The patent provides a kind of umbrella shaped support formula slip casting anchor
Bar, it is made up of umbrella shaped support formula anchor bit, anchor bar body, high score sub-sleeve, stop grouting plug, backing plate, nut, stifled slurry plug, by adopting
The oblique tetrahedron bloom with line tooth is supported with high score sub-sleeve, bloom body is in close contact with country rock, ensure that and work as Anchor Agent
On the premise of failure, anchor pole still can provide the anchor force of end by the oblique tetrahedron bloom supported in umbrella formula, ensure
Anchor pole works on, and the anchor pole reliability is high, and simple to operate, anchoring effect is strong.The umbrella shaped support formula grouted anchor bar is on the whole
The anchoring property of anchor pole is added, good supporting effect has been played in engineering practice.The patent efficiently solves slip casting anchor
Bar allows pressure anchor contact area deficiency of the initial stage of anchoring without first anchor-hold and grouted anchor bar and country rock the problems such as, but how to increase
Bar makes pressure energy power aspect still unresolved.
The content of the invention
In order to overcome existing grouted anchor bar anchored end anchor force deficiency at present and allow the hypodynamic problem of pressure energy, this practicality is newly
Type provides a kind of multistage and allows pressure grouting anchor pole, and anchor pole can be achieved and farthest contacted with country rock hole wall, raising grouted anchor bar
Anchor force and allow pressure energy power.
To solve the above problems, the utility model adopts the following technical scheme that：
（1）Multistage allows pressure grouting anchor pole by anchor rod body, stop grouting plug, clamp nut, anchor rod pallet board, high score sub-sleeve, height
It is strong allow pressing spring, the first branch sleeve, the second branch sleeve, the 3rd branch sleeve, allow pressure support rod body, allow compressed steel body, slip casting
Hole, body of rod drill bit composition.
（2）The anchor rod body inner hollow, multiple injected holes, stop grouting plug, fastening are arranged with outer wall on anchor bar body
Nut pallet and anchor rod pallet board are sequentially nested with the tail end in anchor bar body from the front to the back, and the anchor rod pallet board right-hand member sets high score sub-set
Tin, it is sequentially provided with the first branch sleeve, the second branch sleeve, the 3rd branch sleeve, the 3rd branch sleeve on anchor rod body
Opposite side be provided with anchor bit.It is described it is high-strength allow pressing spring be used for connect the section branch sleeves and anchor bit of left and right two.
（3）Described allow presses support rod body, allows compressed steel body to be arranged on branch sleeve.Allow and press support rod body and allow compressed steel body to lead to
Cross be hinged mode to connect, and fixation is hinged on branch sleeve.
（4）In anchor rod body, high score sub-sleeve, branch sleeve and high-strength coating epoxy polyester mixed type on pressing spring is allowed to prevent
Rotten coating.
The beneficial effects of the utility model are：A kind of multistage provided by the utility model allows pressure grouting anchor pole, can be to supporting
Engineering plays good effect.By pushing up high score sub-sleeve, high score sub-sleeve successively power transmission to the first branch sleeve, the
Two branch sleeves, the 3rd branch sleeve, branch sleeve are moved, by allowing pressure support rod body that compressed steel body will be allowed to be supported in drilling
On wall, make to allow compressed steel body to be in close contact with country rock, ensure that on the premise of Anchor Agent fails, anchor pole still can be pressed by allowing
Steel body provides the anchor force of end, and when surrouding rock deformation is excessive, high-strength in anchor pole allows pressing spring to buffer pressure caused by country rock again
Power, effectively avoid anchor pole from being pulled off, ensure that anchor pole works on, by the coating epoxy polyester mixed type corrosion-inhibiting coating of setting,
Make the anchor pole when complicated geological works, reduce because some corrosive substances contained inside geology make anchor pole by corruption
Lose and be easily broken off, the anchor pole reliability is high, and simple to operate, anchoring effect is strong.
